Reduced Graphene Oxide-Coated CuFeO(2) with Fenton-like Catalytic Degradation Performance for Terramycin

A novel Fenton-like catalyst made of reduced graphene oxide-coated CuFeO(2) (rGO-coated CuFeO(2)) was synthesized by the hydrothermal reaction method to remove terramycin from aqueous solutions. The catalytic degradation performance of rGO-coated CuFeO(2) for terramycin was verified with H(2)O(2) activation. The characterization reveals that rGO-coated CuFeO(2) has a micro- and mesoporous structure, with groups such as C=C/C−C, CH(2)−CO, and HO−C=O found on the surface. The Fenton-like catalytic degradation of terramycin by rGO-coated CuFeO(2) was in line with the pseudo-second-order kinetic model, and the elevated temperature accelerated the reaction. Terramycin was catalytically degraded by rGO-coated CuFeO(2) in two steps: terramycin was first adsorbed by rGO, and then Fenton-like degradation took place on its surface. This research presents new insight into the design and fabrication of Fenton-like catalysts with enhanced performance.
